Witryna14 maj 2024 · The corrosion rate is found to relay on the impurity Fe concentration in the alloys and decreases with decreasing Fe content. When Fe content drops from 150 ppm to 10 ppm, the corresponding corrosion rates under as-cast and solution treatment conditions are reduced from 8.54 mm/a and 8.61 mm/a to 2.54 mm/a and 0.21 mm/a, … Witryna12 maj 2024 · Herein, we report a laser synthesis of BNNTs using only ammonia borane, with reduced impurity contents, especially amorphous boron and the consequent in-situ formation of BNNT fibers. We propose using a molecular precursor, ammonia borane (H 3 N-BH 3 ) that enables independent supply of B-N radicals one by one, analogous to …
